Abstract: An apparatus for photographing a pipe without suspension of water supply and a system for controlling the same are disclosed. According to present invention, the interior of the pipe can be photographed by inserting the camera into the pipe and moving and rotating the camera without halting water supply, and information about the movement and rotation of the camera can be produced. A problem of discontinuance of using the whole pipe due to photographing of the interior of the pipe can be prevented. The camera can accurately photograph respective portions in the pipe by precisely moving forward/backward and rotating left/right or up/down. Since information about a practical position in the pipe with respect to the photographed image is provided, a user can accurately grasp a defect-position in the pipe, and can easily control the camera.

Abstract: Provided is a 2-dimensional virtual array probe for 3-dimensional ultrasonic imaging. The probe includes: an ultrasonic transducer; a metallic probe body including an ultrasonic wave emission surface in which a plurality of wave-guides are arranged in 2-dimensional array and a ? sphere-shaped recess for irregularly reflecting ultrasonic wave emitted from the ultrasonic transducer in an inside thereof; a piezoelectric sheet arranged on the ultrasonic wave emission surface to make contact with an object to be inspected and configured to pass the ultrasonic waves emitted from the probe toward the object to be inspected and output a signal by detecting the ultrasonic waves reflected from the object to be detected; and a control unit configured to control the ultrasonic transducer so that the plurality of wave-guides sequentially generate ultrasonic wave.
